Hey hope this is the correct channel for this question.. I'm trying to compile my app using defmt package. All's well untill I try to compile in using `DEFMT_LOG=info cargo build`, I get the following output:
```

Related stuff in my cargo.toml:
```
defmt = "0.3.2"
defmt-rtt-target = "0.3.0"
rtt-target = "0.3.1"
panic-rtt-target = { version = "0.1.2", features = ["cortex-m"] }
```

Any ideas where to look?
